Electrochemical Characterization

How active is your catalyst? Does it display a high surface area? What about stability? How is it compared to state-of-the-art?

Electrochemistry is a powerful tool that allows us to determine important properties of electrocatalysts, such as active surface area or catalytic activity. These analyses are typically performed in three-electrode cells, where the voltage against a reference electrode is measured while a current is applied between a counter and a working electrode.

Fully automated electrochemical setup

At the Danish Technological Institute, we have a fully automated electrochemical setup, which allow us to perform measurements on seven different samples simultaneously. The setup includes the possibility to introduce different gases during the electrochemical measurements. In addition, the setup has four rotating electrode speed units for activity measurements (Rotating Disk Electrode – RDE) controlled by mass transport.

DOE recommended and customized protocol

We have standardized protocols for activity and stability measurements of catalysts in multiple electrochemical reactions (e.g. fuel cells and electrolysers), that follows the DOE recommendations. We can also provide with development of customized procedures for the individual customer cases.

We can measure on particles, wires and polycrystalline surfaces, in both acid and alkaline media.

Combined analysis methods give the best resultsAt the department for Nano Production and Micro Analysis at Danish Technological Institute, we have more than 25 years of experience solving characterization tasks for our customers.

We often combine results from several separate types of state of art characterization equipment and can offer you a design of experiments that suits your materials requirements, in a short delivery time.
